Probit Analysis Approach on Performance of Toxicity in Freshwater Fish

ZOOLOGY

The probit analysis approach was used to perform the acute toxicity bioassay on textile industrial effluent (TIE). The LC50 values were found to be 56.23 percent, 28.84 percent, 22.38 percent, and 16.59 percent after 12, 24, 48, 72, and 96 hours. There was a considerable reduction in LC50 readings as effluent concentration rose. A 32.88 percent safety margin was determined. With increasing toxin concentration, the experimental fish C. batrachus displayed more stressed behavioural patterns. The acute toxicity of textile-based industrial effluent caused the experimental fish C. Batrachia to exhibit excessive mucus production, uncoordinated and tailfin movement, surface, loss of buoyancy, escape propensity, hyperactivity, and discoloration of the skin. All treatments had some level of mortality, with the exception of the control. C.batrachus experimental fish exposed to textile-dyeing effluents were also subjected to a hematological examination. Hb, RBCs, WBCs, PCV and MCHC of the test species were analysed using hematological data. It's been brought out that these settings might be tweaked. As a result, it may be determined that the TIE is harmful to fish and other aquatic life.
